Definitions

  • DE-PS 34 46 666 discloses a soil conditioner which contains a particulate polyelectrolyte in granule form serving as a water retention agent.
  • This water retention agent has a high degree of water absorption and water storage capacity and is able to absorb and retain many times its own weight in water. The particles of the granulate pass into a hygrogel and swell up.
  • the invention has for its object to provide a soil conditioner, which is particularly applicable in infertile applicable soil types with predominant sand content and there allows plant growth with appropriate irrigation.
  • the invention proposes to add to the water retention agent a soil activator, which on the one hand causes oxygenation of the soil and on the other hand enables the digestion of plant nutrients in the soil. It has surprisingly been found that when such agents are added, plant growth can be ensured even in soils considered infertile. Obviously, especially in drylands and desert areas, sufficient nutrients are contained in the soil to allow plant growth. However, these nutrients are not easily accessible to the plants, so they must first be unlocked.
  • the soil activator may be in powder form.
  • the soil activator powdery or dusty envelops the individual bodies of the water retention granules and reliably wherever wherever the granules are introduced, enters the soil, so that a synergistic effect between the water retention agent on the one hand and the soil activator on the other hand can be guaranteed.
  • the very small surface of the powder or dusty components of the soil activator causes a large reactive surface of this material, so that the soil activator is particularly effective.
  • the granules, which is the water retention agent have a volume fraction of about 50% of the soil conditioner. Experiments have shown that good results can be achieved with such a mixing ratio.
  • the soil activator may contain rock flour.
  • This stone powder is a carrier of minerals that promote plant growth.
  • the soil activator contains phosphorus-containing rock flour, so that the soil activator also has a fertilizing effect.
  • rock flour which merely serves as a carrier of minerals
  • another type of rock serves as a phosphorus carrier, so two different types of rock flour are included in the soil activator.
  • the soil activator may contain dried fermented cereals containing the lactic acids of the soil activator.
  • Suitable water retention agents are granules which are commercially available under the name "Aquaprotect” and contain a particulate polyelectrolyte which consists of at least one crosslinked, water-only swellable polymer based on acrylic acid, methacrylic acid, acrylamide, metacrylamide, acrylonitrile These polyelectrolytes change into a hydrogel upon contact with aqueous liquids and can reversibly sorb and desorb more than one hundred times their own weight of distilled water or more than seventy five times their own weight of a standard fertilizer solution synthetic silica on. It can be advantageously provided to use this polyelectrolyte in a proportion of 0.3 to 1 g, in particular 0.3 to 0.6 g per liter of soil mass to be improved.
